JAMES HANSEN, OF DELAVAN, VISOONSIN.

VAT AND CHURN.

SPECIFICATION forming part of Letters Patent Noa 449,321, dated March 31, 1891.

Application filed April 11, 1890. Serial no. 347,559. (No model.)

To all whom it may concern.-

Be it known that I, JAMES HANSEN, a citizen of the United States ofAmerica, residing at Delavan, in the county of Walworth and State of Wisconsin, have invented a new and useful Improvement in Cream-Ripening Vat and Churn Combined,of which the following is a description, reference being had to the accompanying drawings, the same forming part of that description.

My invention has special reference to an improvement in working body-churns, and the object sought to be accomplished is to produce a combined cream-vat and churn which can be cheaply and easily manufactured and conveniently and readily used to effect the desired results.

lVith these ends in View my invention consists in certain peculiarities of construction of parts more fully described hereinafter, and pointed out in the claim.

Referring to the accompanying drawings, Figure 1 represents a front elevation of my complete device, shown in closed and compact adjustment and in condition for the churning operation to take place; Fig. 2, a longitudinal section of the same; Fig. 3, an end view; Fig. 4, a transverse section; Fig. 5. a top or plan view with the cover removed and a portion of the vat broken away; Fig. 6, a detail view of the spiral-like strip or way down which the water flows; Fig. 7, a modification of the same, and Fig. 8 a top view of the water-pan.

The body portion of the churn consists of a rectangular box or receptacle B, suitably mounted in a frame A and closed by a cover or lid 0 of similar shape and form, and said receptacle B is provided on the inside with a metallic lining b, which closely fits its side walls, but is arranged on an incline over the bottom of the receptacle for a purpose here inafter explained. An offset a is formed around the inside of the upper portion of the box B, and the upper edge of the lining is turned down upon said offset and there secured, as more clearly seen in Figs. 2 and 4.

The cream -vat consists of a rectangular metallic pan or vessel D, which fits Within the box B, butis of such size as to leave a space lic vessel are provided with a flange f,-projecting from its upper edge beyond the offset a and fitting against the lining b, as seen at 0, Figs. 2 and 4, where it may be secured to said lining in suitable manner. It will thus be seen that a rectangular groove is formed by the projecting flangefand the offset a, and in this groove is fitted the flange c of the cover or lid 0, and thusa tightjointis formed between the latter and the body portion B. These two parts are securely clamped together by jointed frames (Z and 0 while the churning is in progress.

As has been previously mentioned, the vat D is spaced from the sides and bottom of the box B, and in the side spaces thus formed a spiral-like strip 9 is fitted, being secured to the lining b, and said strip commences at the upper right-hand edge of the churn-box, opposite an inlet-orifice h, and thence leads on an incline twice around the vat, terminating directly below its starting-point and resting upon the bottom of the receptacle B. Thus this strip 9 forms a channel between the vat and churn-box, down which water introduced through the orifice 72, will flow to the bottom of the box B. In Fig. 7 a modification of this arrangement is shown, in which a series of separate inclined angular strips 70, Z, m, and n are employed, a number of such strips being arranged on opposite sides of the creamvat, and being adapted to convey the-Water around the latter in opposite direction, said water being introduced through a T-pipe in serted through the aperture h, as seen in Fig. 8. Where the strip g terminates it leads through an opening 15 into a waterpan E, which rests upon the inclined bottom lining b, and thus will convey the water led into it by the stripg to its opposite lower end. This water-pan is of rectangular form, and is provided with a series of equidistant partitions 19, alternately spaced from the opposite sides of the pan, and thus forming a circuitous channel 3, down which the water flows to the lower end of the pan, where it discharges through an opening to, and thence out of the churn through the orifice 2'. Hence the water can circulate freely around all the sides of the vat and beneath the bottom of the same, thus acting to keep the cream at the proper temperature to bring it to the neces sary condition for churning and producing butter of good quality;

A discharge-orifice "u is made in one side of the boX B and vat D, and the buttermilk is drawn off through this opening after the butter has been made.

The preferred construction of my device having been set forthI will now proceed to describe its operation. The fresh cream is first put in the vat D and a stream of hot or cold water caused to constantly flow around and beneath said vat, discharging through the orifice "L. This process is continued until the cream is brought to the proper condition for churning,when the cover 0 is securely clamped to the boX B and motion imparted to the churn to agitate the cream contained therein.

When the butter has come, the churn is brought toa standstill with the vat on the lower side, and the buttermilk is drawn off through the discharge-orifice o. The next step is to pass a current of ice-cold Water around the vat to cool the butter contained in the same, after which the churn is given a half-turn to bring the cover on the under side when the butter will drop from the vat into said cover. The latter with its contents is then removed and the butter subjected to a process of working to bring it to the proper condition for placing upon the market. Thus I produce a simple and compact arrangement, which can be effectively employed as a vat in Which the cream can be treated preparatory to churning and then converted into a churn in which the butter is made.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is Y The herein-described apparatus for making butter, the same consisting of a churn-box B, having an inside lining b, with an inclined bottom I), a removable cover 0 for said box, a cream-vat D, contained within the latter and spaced from the sides and bottom thereof, an inclined strip g, contained in the side spaces thus formed and adapted to convey Water introduced through an orifice h in said churn-box around the vat, and a water'pan E, resting on said inclined bottom lining Z) and adapted to receive water from said inclined strip g and lead it through a tortuous channal formed by partitions P, discharging through an orifice t in the lower portion of the churn-box, all arranged and adapted to operate in the manner and for thepurpose described.
